No, don't do that. If you try to do this, the consequences are described before you commit.
It's kind of you to post back. I don't understand why you've had this problem. My wife who has an iPhone X, and on my iPhone 11 Pro, the settings are as I described to you, work fine.
One option offered to you in Settings > Face ID & Passcode is to "Reset Face ID". This lets you start afresh and redo your Face ID. That may help. Curiosity gets the better of me and I'm at a loss to explain your dilemma.
I suppose that after following the my earlier post, you rebooted the iPhone?
Do please keep in touch because although I've not solved your problem, other members may chime in. All I can say is that the course you followed should have worked.
This is a screenshot from my iPhone 11 Pro:
I take it that is what you too, are seeing?
